As shown in fig. 1 to 3, the ball sleeve tool convenient to mount and use according to the utility model comprises a sleeve body 1 with a cylindrical shape, wherein one end of the sleeve body 1 is provided with an insertion hole 2 for facilitating insertion of a screw, the insertion hole 2 is matched with the head of the screw 3, the peripheral side part of the sleeve body 1 is provided with at least two containing grooves 4 uniformly distributed around the axis circumference of the sleeve body 1, each containing groove 4 is communicated with the insertion hole 2 through a sliding through hole 5, the sliding through hole 5 extends along the radial direction of the sleeve body 1, a sliding limiting piece is connected in the sliding through hole 5 in a sliding manner, the sliding limiting piece is pushed by a pressed elastic piece arranged in the containing groove to extend into the insertion hole 2, and one end of the sliding limiting piece extending into the insertion hole 2 is used for being clamped at the lower end of the head of the screw 3 so as to buckle the head of the screw. Normally, the compression elastic piece pushes the sliding limiting piece to move along the sliding through hole by virtue of self elasticity until the inner side end stretches into the insertion hole; when the head of the screw is inserted from the insertion hole, the head of the screw pushes the sliding limiting piece to move towards the accommodating groove along the sliding through hole, and the compression elastic piece is compressed at the moment; after the screw is inserted in place, the sliding limiting piece is not extruded by the screw head, the compression elastic piece pushes the sliding limiting piece by means of self elasticity, the sliding limiting piece moves to the inner side end along the sliding through hole to extend into the insertion hole, one end (namely the inner side end) of the sliding limiting piece extending into the insertion hole is clamped at the lower end of the screw head, and at the moment, the screw head cannot easily fall from the insertion hole, so that the screw head is buckled.

In this embodiment, the compression elastic member is an arc-shaped spring piece 6, the spring piece 6 is fixed at one end of the accommodating groove 4 far away from the sliding through hole 5, and the spring piece 6 stretches along the radial direction of the sleeve body 1.

In this embodiment, the sliding limiting member is a ball 7, and an outer end of the ball 7 abuts against the middle of the spring piece 6. The elasticity of the spring piece is utilized to relax, the height of the ball is improved, the sleeve is realized to fast buckle the screw and the nut, and the installation is convenient.

In this embodiment, the sliding through hole 5 is a tapered hole with a small inner end diameter and a large outer end diameter, the inner end diameter of the sliding through hole 5 is smaller than the diameter of the ball 7, and only a part of the ball 7 extends out of the sliding through hole 5 under the pushing of the spring piece 6 so as to limit the ball and prevent the whole ball from falling into the insertion hole.

In this embodiment, the depth of the insertion hole 2 is greater than the height of the head of the screw 3; when the screw is inserted to the bottom, the head of the screw is positioned above the ball.

In this embodiment, the cross-sectional shape of the insertion hole 2 may be hexagonal in shape in accordance with the shape of the head of the screw 1.

The specific implementation process comprises the following steps: taking a screw 3 with a nut 8 as an example: inserting the screw 3 from the insertion hole 2, and pushing the ball 7 to move (i.e., move outwards) along the sliding through hole toward the accommodating groove 4 by the nut 8, wherein the spring piece 6 is pressed by the ball 7; after the screw 3 is inserted in place, the balls 7 are not extruded by the screw cap 8, at this time, the spring piece 6 pushes the balls 7 inwards by means of self elasticity, the balls 7 move along the sliding through hole 5 until the inner side ends extend into the insertion hole 2, one end (i.e. the inner side end) of the balls 7 extending into the insertion hole 2 is clamped at the lower end of the screw cap 8, the screw cap 8 is buckled, and at this time, the whole screw 3 cannot easily fall from the insertion hole 2.
